CASTING BOX non rninrnns.

Application filed May 6, 1927. .Serial No. 189,236.

This invention relates more particularly to a device or machine for casting printers furniture, bases or mountings for cuts, and electrotypes, and stereotype plates.

One of its objects'is the provision of a simple, inexpensive and elficient device of this character by which the printer can readily produce his own furniture, mount-1 ings and plates, and which does not require skilled workmen to operate 1t.

Another object of the invention is to provide a casting box which is readily adjustable to adapt itself to-the classes of work mentioned and which is so constructed and organized as to enable different sized furniture to be cast at the same time.

A still further object is to provide positive'and reliable means for uniformly releasing or ejecting the finished casting from the box. Y

In the accompanying drawings Figure 1 is a front elevation-of a casting box embodying my invention. Figure'2 is a fragmentary side view thereof. Figure 3 is an enlarged fragmentary transverse vertical section on line 8.3, Fig; 1. Figure4 is an enlarged horizontal section on line H, Fig. 1. Figure 5 is a vertical section taken in the planev of line 5--5, Fig. 4. Fig: ures 6 and 7 are perspective views of the companion ejector bars. Figure 8 is a perspective View of one of the division strips or partitions. Figure?) is a perspective view of a piece of furniture cast in the improved box. I l

Similar characters of reference indicate corresponding parts throughout the several views.

In the preferred embodiment of the inventionshown in the drawings, the various parts of the device are supported on a suitable frame consisting of A-shapedmembers 10, 10 between which is disposed a substantially rectangular cast iron plate 12 constit-uting the base of the casting box. This base plate is supported in a slightly inclined pos tion on lugs or ledges 13 formed on the front legs of the A-frames, as shown in Fig. '3. The front face of the base plate has a-series of intersecting vertical and horizontal casting or furniture-forming grooves or cavities 14, 15 which are spaced at different distances 7 apart and may be graduated according to the printers measure so that any combinat on of them may be used atone time for casting furniture and the like of diflerent sizes, as to both length and Width. :Theresulting wardly to provide the necessary'drajft in effecting the ready removal of the castings therefrom, the latter being-formed between at least two adjoining grooves and the bosses functioning ascores to make the furniture plate mounts andstereotypes lighter and to reduce the amount of casting metal employed to a minimum. Along its opposite marginal sides the base plate has forwardly-facing up right channelsor guideways 17.

Removably applied over the front face of the base plate 12 isv a cover plate 18, these parts forming the bottom and top walls-of the casting box into the grooves 14, 15 of which the casting metal is adapted to be poured thru an inlet opening 20,.as-shown in Fig. 3. The cover plate may be detachably held in place by looking bolts 21, 21

guided in lugs 22 formed at the opposite sides of said plate andadaptedto engage open ngs 28 formed .in flanges 24 projecting from the front edges of the A-frames' 10.

P TENT' F- CBIr bosses or projections 16 formed by these in a tersecting grooves are slightly taperedout- WVhile these bolts may be actuated in any suitable manner, crossed hand levers 25 are preferably employed which are pivoted at theirinner ends to the locking boltsfor conable castings of various heights to'be made,

the outer ends of the bolts which pass thru the openings 23 are tapered or wedge-like in shape.

For the purpose of blocking off or adapting the various grooves or cavities 14, 15 to make'furniture, plate mounts and stereotypes of diiferent sizes, vertical andhorizontal walls, partitions or division strips 26,

ve niently actuating them and also for facil- 27 are employed which are made in various lengths and heightsand which are adapted to be removably mounted in said grooves for and centrally of the intersecting grooves 14,

15 and are provided in their bottom edges with longitudinalchannels or grooves 28 exforming the two sides and an end wall of the 1 mold. These strips are disposed edgewise terseoting grooves.

and any two of such upright. strips, which a. I11... 211 constitute the side walls of a given indld, are

supported at their lower ends on corre sponding horizontal strip which formsthe lower end wall of said mold; lVhen castings of different heights or thicknesses are desired, division strips of .a corresponding height are employed and the cover plate 18 can be readily in g bolts 21. p

Means "are provided for facilitating the removal of the finished castings from the boic and for this purpose ejecting devices are employed which operate in conjunction withthe division strips to release the castings from the bosses 16 of the base plate 12. Theseejecting devices preferably consist of two sets of relativ'ely movable over lappingbars 30, 31 located at opposite sides of the box .a'ndf'seated in the guidewa'ys 17 in the marginal sides of the base plate, as shown in Figs. 1 and 4. The inner bar 30 of each set normally projects with its front edge forwardly of the face of said base plate and is provided in such edge with notches 32 in which the base portions of the horizontal division strips 27 are seated "and held against vertical displacement in the casting box, as seen in Fig. 7. Said inner bars 30, While free to move as a unit laterally of the companion bars 81 and forward and backward relative to the base plate, are held against vertical movement relative to'such parts by "a tie member or bar 33 which rests on the top edge of said plate and engages corresponding grooves '01 recesses 34: in the opposing inner facesofthe inner ejector bars. In their outer sides, the latter are provided with rearwardly-facing inclined teeth or cam faces 35 and the'outerejector bars 31 are provided in the adjoining inner sides with companion forwardly-facing inclined teeth or cam faces 36. These outer bars project above the inner bars and are normally supported and held against "slipping downwardly by the teeththe'reof engaging the corresponding teeth of the companion inner bars, in 'the'i'nanner shown in Fig. 5, and they'a're capable of movement lengthwise in their guideways 17 relative to said inner bars but are prevented from outward displacement relative thereto. *iy forcing the outer bars downwardly, the

con'i'panion' inner bars are moved outwardly and carry the division strips 2'7 therewith, with the result that the castings are disengaged orfrele'ase'd from the molds.

To effect the unifornrand'ready downward movement of the outer ejector bars when it isdesiiedto remove the finishedcastinga'a liori'zdnta'l e erating shaft 37 is provided which is 'joarnaled at its ends in the upper ends of 'tlie "A-frames 10 and has cams '88 thereon arranged to engage the upper ends of adjusted to them by the locksaid bars. A handle 39 is attached to the shaft tooperate it. Springs 40 fastened at their upper ends to the frame 10 and at their lower ends to lugs l1 formed on the outer bars 31, serve to constantly urge the latter to their elevated normal position. In order to positively insure the withdrawal of the castings from their molds asthe ejecting mechanism is operated the divisions strips 26, 27 have laterally-projecting lugs or feet 42 on the opposite sides of their lower edges, as shown in Figs. 3, 4, and 8. By the provision of these lugs, as the ejector bars 30 actuatedto force the divisionstrips outwardly, the lugs on the latter function to pry or raise the castfrom the bottoms of the molds.

In using this casting box, assuming the cover plate 18 to have been removed, the division strips 26, 27 are placed in casting grooves '14 to block the same off so as to produce the particular size or sizes of furniture, plate mounts or stereotypes desired, the strips being adjustable on the base plate 12 so that various sizes of furniture can be produced at any one time. After arranging the strips as desired, the cover plate is applied and locked in position by the bolts 21, 21, whereby molds are produced to cast the corresponding furniture. The casting metal is then poured into these molds thru the inletopen-ing 20, and after the same has cooled sufliciently, the cover plate is removed, the cam shaft 37 is rocked forwardly to lower the ejector bars 31 and force thecom-pa-nion bars 30 outwardly to release the finished castings 13 from the ,base plate in the manner heretofore described.

This improved casting box is simple, compact and inexpensive in construction, it is readily adjustable for making printers furniture of different sizes as wellas mountings for "electrotypes, and stereotype plates, and

it is easy to operate.

It will be understood that the embodiment of the 1nvent1onherc1n shown and described -isillustrativeofo-ne form and that the invention maybe incorporated in other forms and various changes in the construction thereof may be made within the scope and spirit of the appended claims.
